Abstract: A data flow processing system represents processing by a directed graph including processing nodes that generate, and process, groups of dependent messages and that can process such groups of messages in order. To identify a group of messages, the system applies message identifiers to messages. Processing of a message may generate child messages. A child message is assigned a message identifier that incorporates the message identifier of the parent message. The message identifier of the parent message is annotated to indicate the number of related child messages. The processing node maintains a buffer to store messages in the group. When a message is received, its message identifier indicates whether it is in a group and information about the group. From this information the processing node determines whether all messages within the group have been received, at which time the processing node can process the messages in order.

Abstract: A highly parallel, asynchronous data flow processing system in which processing is represented by a directed graph model, can include processing nodes that generate, and process, groups of dependent messages and that process messages within such groups in order. Other messages can be processed in whatever order they are received by a processing node. To identify a group of dependent messages, message identifiers are applied to a message. Processing of a message may generate child messages. A child message is assigned a message identifier that incorporates the associated message identifier of the parent message. The message identifier of the parent message is annotated to indicate the number of related child messages. When a group of messages is to be processed by a processing node in order, the processing node maintains a buffer in which messages in the group are stored.

Abstract: A golf club head is composed of a first body having mass concentrations at the heel and toe ends joined by a relatively thinner central web portion that is recessed from the front, top and rear surfaces of the club head. A second body member selected from a plurality of second body members composed of a relatively less dense material is temporarily attached to the web portion of the first body to form a face portion that extends from the sole to the top rail of the club as well as the central portion of the top rail.

Abstract: Messages are processed to guarantee proper work scheduling and allow for cyclic and conditional processing. A processing node requiring ordered processing of messages is configured to operate within a plurality of successive processing nodes not requiring ordering processing of messages. Nodes upstream of the ordered node (i) monitor skew between the messages being processed and messages that are ordered after the messages still being processed and that have been forwarded downstream of the node and (ii) pause processing upon reaching skew limits. The nodes upstream of the ordered node limit output of messages to be within a delta of other messages as defined by message IDs. In addition, messages removed from a flow path are replaced by Null messages for ordered processing. Child messages are encoded to incorporate parent IDs preserving ordering systems.

Abstract: A shutter device is provided for a bypass isolation automatic transfer switch. The shutter device comprises a frame and a shutter that is movably supported by the frame and that is configured to selectively cover and uncover conductors. At least one cam is movably supported by the frame and at least one shutter lever is interposed between the shutter and the at least one cam. The shutter lever is configured to move the shutter in response to movement of the cam.

Abstract: An Automatic Transfer Switch (ATS) having a switch configured to connect one of two sources to a load, a mechanical drive, an actuator, and a solid state control relay is disclosed. The mechanical drive is configured to drive the switch between a first position and a second position, the first position connecting the switch to the first source, and the second position connecting the switch to the second source. The actuator is in mechanical communication with the mechanical drive to cause the mechanical drive to move on command. The solid state control relay is responsive to an external signal and productive of a control signal, wherein the actuator is responsive to the control signal to cause the mechanical drive to move.

Abstract: A golf club head is formed of a hollow body, the rear body portion of which includes a metallic stringer that extends along the crown-skirt interface and a plurality of ribs intersecting the metallic stringer to form a lattice frame, the openings of which are filled with an organic composite material such as graphite epoxy. An additional aperture formed in the skirt is also filled with the same graphite epoxy material. Because the graphite epoxy is lighter than the surrounding metal frame, the rear body portion of the golf club head is lighter than a comparable all metal club head. Yet, the presence of the metallic stringer and frame renders the metal-organic composite rear body portion substantially stiffer than a comparable all-composite rear body portion.

Abstract: A golf club head is formed of a hollow metal body having a center of gravity that is above the geometric center of the club face. The hollow metal body of the club head has a sole plate that is smoothly contoured and devoid of any inefficient structures such as weight pads or other mass concentrations. By avoiding the use of inefficient structures such as weight pads, more material is available for the structural walls of the club head body while maintaining the club head within acceptable weight limitations. Moreover, placement of the center of gravity above the center line of the face ensures that sufficient backspin will be imparted to the golf ball when struck by the club.

Abstract: An automatic transfer switch and protection device is provided. The device includes a contact, a drive assembly, and a controller. The contact is movable among a first position, a second position, and a third position. The drive assembly moves the contact among the first, second, and third positions. The controller receives a first signal indicative of a condition of power in a first power source and a second power source. The controller provides a second signal to the drive assembly to move the contact in response to the first signal. The contact can provide power to a load from the first source in the first position, from the second source in the second position, and can isolate the load from the first and second sources in the third position.
